FASTENING-CLIP FOR WIRE-TERMINALS.

Application filed July 5, 1912, Serial No. 707,655. Renewed August 12,1916. Serial To all'whom it may concern:

Be it known that I, CHARLES W. BECK, who am a citizen of the UnitedStates of America, residing at Detroit, in the county of Wayne and Stateof Michigan, have invented certain new and useful Improvements inFastening-Clips for Wire-Termi- A nals, of which the following is aspecification.

This invention relates to fastening clips for the terminals of currentcarrying wires, and has for its object an improved device of this typeadapted especially for the firm, though easily detachable, connection ofa current wire to some such terminal as the stem of a spark plug.

In the drawings:

Figure 1 is a plan view of a clip member and its adjacent cable end,wherein the stem portion of the clip directly. engages the cable wirewithin the end. of an insulating outer wrapping.

Fig. 2 is a side elevation of the device shown in Fig. 1, partly insection.

Fig.3 is a plan view of a somewhat modified form, wherein thewire-engaging portion is similar to that of Figs. 1 and 2, while thestem-engaging resilient portion is unitary with the resilient side armsor brackets, and is stamped to form from a unitary piece of metal.

Fig. 4 is an end elevation of the form of device illustrated in plan inFig. 3.

L represents a threaded stem member whose bored central portion isadapted to receive the end of the wire B, while the rubber or otherinsulating part of the cable engages about the stem L, whose enteringend is preferably beveled as at M to facilitate its being forced intothe cable end, and about the wire. The solid head N of this stem memberis of substantially the same size as the cable member A including theinsulating outer wrapping, and extends across the end thereof. Throughthis solid head N engages a U-shaped resilient piece to each end ofwhich is riveted or otherwise attached a jaw member V, whose opposinginclined edges II are adapted to be forced about the stern of a sparkpineal-"other" s'imilar'member distance between the points J. The slightthan the Specification of Letters Patent. Patented Feb. 27, 1917.

yielding of the jaw members, because of the resiliency of theirsupporting parts P, enables the post to slip past the point J and intothe relatively round space K, which is of slightly greater diameter thanthe distance between these points, and from which position only a strongand intentional pull upon the clip member, or upon the cable end withwhich it is connected, will detach it.

Fig. 3' shows a somewhat modified form in which the parts correspondingto the U- shaped piece P and the jaw members V are in a singlestamped-out piece Y, the base or branch portions Q being bent so as tobe inserted sidewise in the kerf R in the head end of the stem. theplane of the jawportions S being substantially perpendicular to that ofthe flexing branch portions Q, though having the same inclined outeredge portions as the form of the jaws shown in Figs. 1 and 2.

That I claim is:

1. A fastening clip, comprising an attaching section, a resilientU-shaped bracket connected to said attaching section provided with jawmembers at the outer ends of the arms of said bracket, said jaw membersextending transversely of the planes of said arms and having theiropposing edges angularly inclined toward one another, with thoseportions of their opposing edges next within said inclined portionspartially surrounding an included rounded space.

2. The combination of an attaching section, a U-shaped bracket havingthe base thereof connected to the attaching section, said bracketprojecting outwardly from the attaching section, and jaw members carriedby and extending inwardly from said arms having cotiperating bearingportions on their opposed edges, there being an entrance opening leadingfrom the forward ends of said jaws to the bearing portions, and the armsof said bracket being resilient and adapted to movesaid jaws toward oneanother.

In testimony whereof I ailix my signature in presence of two witnesses.
